Moisturized air-filter for internal combustion engines

An apparatus for moisturizing air for an air intake of an internal combustion engine, comprising:

• container means forming a chamber holding a quantity of water to only partially fill same so as to leave an air passageway above the water;
• air inlet means for admitting air into the container means at one area thereof and communicating with the air passageway;
• discharge means for discharging air from an area of the container means remote from said inlet means and communicating with the air passageway for conveying moisturized air from the chamber to an internal combustion engine air intake;
• said air inlet means comprising a tubular member, sealingly secured to an opening in the container means, with a portion thereof extending internal to the container means;
• and
• said portion internal to the container means having a semi-tubular portion removed on a side which is opposite to the discharge means thereby forming a substantially horizontal wall surface which is below the opening, at its lowermost point, in the container means and a remaining semi-tubular portion which extends substantially below the water surface in such a manner as to partially segregate the container means into two areas and forming a passageway below the water surface permitting communication between said areas of the container means.
